Description

Technical Field

[0001] This utility model relates to the field of reheater piping technology, specifically a boiler reheater piping fixing mechanism. Background Technology

[0002] A reheater is essentially a steam superheater that reheats low-pressure steam that has already done work to a certain temperature. The reheater further improves the thermal efficiency of the power plant cycle and keeps the steam temperature of the turbine's last-stage blades within an allowable range. The reheater has multiple pipes installed inside to achieve heat exchange.

[0003] Authorized announcement number CN220397491U discloses a boiler reheater pipe fixing mechanism. This device mainly uses a movable clamping block with a positioning plate, allowing the positioning plate to pass through a fixed clamping block. A spring then pushes the fixed plate into the positioning plate, pressing and fixing it, thereby installing the movable clamping block on one side of the fixed clamping block and securing the reheater pipe. This solves the problem that fixing the fixed and movable clamping blocks with four second positioning bolts and nuts requires rotating each of the four nuts individually, which is cumbersome and affects installation efficiency. However, in actual use, the device still has the following drawbacks:

[0004] The aforementioned patent mainly improves the installation efficiency of reheater pipes by fixing them with positioning bolts and nuts. However, in the actual assembly of reheater pipes, the pipes are usually connected in a U-shape. However, it is difficult to adjust the position of the pipe fixing structure according to the spacing of the U-shaped pipes, which increases the difficulty of pipe fixing and reduces the efficiency of pipe installation and fixing. Since there are many connections of reheater pipes, the installation process is complicated and inconvenient. The actual assembly requires each set of fixing structures to be individually threaded, which greatly increases the labor required for pipe fixing and increases the limitations of fixing structure operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3The present invention provides an embodiment of a boiler reheater pipe fixing mechanism, comprising a lower mounting base 1 and an upper mounting base 2. The upper mounting base 2 is provided with a mounting chamber 3 at its top. A threaded rod 6 is fitted on the bottom of one side of the lower mounting base 1. A matching internal threaded sleeve 5 is fitted on the outside of the threaded rod 6. A handle 7 is fitted on one side of one end of the lower mounting base 1, and one end of the handle 7 extends into the interior of the lower mounting base 1 and is provided with a toothed plate 12 that meshes with the threaded rod 6. The toothed plate 12 includes a first bevel gear and a second bevel gear. The first bevel gear is provided on one end of the handle 7 that extends into the interior of the lower mounting base 1. The second bevel gear that meshes with the first bevel gear is provided on the bottom of the outside of the threaded rod 6. The meshing linkage of the two sets of bevel gears facilitates the rotation of the threaded rod 6 by the handle 7. The internal threaded sleeve 5 is connected to the upper mounting base 2.

[0025] A guide post 15 is installed on the side of the lower mounting base 1 away from the internal threaded sleeve 5, and a guide hole is opened on one side inside the upper mounting base 2. The upper mounting base 2 slides up and down on the outside of the guide post 15 through the guide hole.

[0026] Guide rods 10 are installed inside the lower mounting base 1 and the upper mounting base 2, and two sets of guide tubes 11 are respectively sleeved on the outside of the two sets of guide rods 10. The top of the two guide tubes 11 is provided with a first clamping seat 8, and the bottom of the two guide tubes 11 is provided with a second clamping seat 9.

[0027] An adjusting bolt 13 is fitted in the middle of the installation chamber 3. An internally threaded sleeve 14 is fitted on the outside of the adjusting bolt 13. A toothed plate 12 is connected to the bottom of the internally threaded sleeve 14. A toothed block 16 is provided on the top of the two guide tubes 11 inside the upper mounting base 2. The toothed block 16 is fixedly engaged with the toothed plate 12. Telescopic rods are provided on both sides of the top inside the installation chamber 3. The telescopic rods are connected to the toothed plate 12 to facilitate the limiting of the toothed plate 12 and to make the toothed plate 12 vertically rise and fall under the limiting guidance of the telescopic rods.

[0028] The upper mounting base 2 is provided with splicing mechanisms 4 on both sides;

[0029] The splicing mechanism 4 includes a slot 401, a positioning element 402, a locking block 403, and a positioning hole 404. The slot 401 is provided on one side of the upper mounting base 2, and the positioning element 402 is fitted inside the upper mounting base 2 on one side, and the positioning element 402 extends to the inside of the slot 401. The locking block 403 is installed on the other side of the upper mounting base 2, and the positioning hole 404 is provided inside the locking block 403.

[0030] The slot 401 is a right-angled trapezoidal slot, the block 403 is a right-angled trapezoidal block, the positioning element 402 is a positioning bolt, and the positioning element 402 is threadedly matched with the positioning hole 404, which facilitates the use of the snap-fit ​​fixing structure to promote the combination and splicing of the upper mounting base 2 of multiple fixing structures.

[0031] Example 1, as Figure 1-2As shown, the slot 401 is a right-angled trapezoidal slot, the block 403 is a right-angled trapezoidal block, and the positioning element 402 is a positioning bolt. The positioning element 402 is threadedly matched with the positioning hole 404. The right-angled trapezoidal block 403 is inserted into the slot 401, which facilitates the splicing of multiple sets of upper mounting seats 2. The positioning element 402 is positioned by the thread of the positioning hole 404, so that multiple sets of upper mounting seats 2 can be synchronously adjusted by the threaded lifting structure of a set of threaded rods 6 and internal threaded sleeves 5, which increases the convenience of multiple fixed structure operations.

[0032] When lifting and lowering is performed using the threaded structure of a set of threaded rods 6 and internal threaded sleeves 5, guide structures for sleeves and rods can be set for the remaining sets of internal threaded sleeves 5 and threaded rods 6 to prevent multiple threads from obstructing each other.

[0033] Example 2, as Figure 1-3 As shown, splicing plates are provided on both sides of the two first clamping seats 8, and the splicing plates have snap grooves inside. Splicing blocks are provided on both sides of the two second clamping seats 9, and the splicing blocks have press buckles inside. By using the structure of snap grooves and press buckles, it is convenient to fix the press buckles in the snap grooves by pressing after the first clamping seats 8 and the second clamping seats 9 are closed to fix the pipe. This eliminates the need for the existing threaded fixing structure and achieves a more efficient and faster reheater pipe fixing operation.

[0034] Working principle: In the reheater piping fixing mechanism of this boiler;

[0035] When installing and fixing the reheater pipes, firstly, rotating the handle 7 engages the toothed plate 12, forcing the threaded rod 6 to rotate. This causes the internal threaded sleeve 5, under the limiting action of the guide post 15, to cause the upper mounting seat 2 to adjust vertically with the internal threaded sleeve 5. This allows the two sets of first clamping seats 8 and second clamping seats 9 to open. At this point, the reheater pipes can be inserted into the inner side of the first clamping seat 8. Then, according to the spacing of the reheater pipes, the first clamping seat 8 is slid and adjusted to a designated position under the guidance of the guide tube 11 and guide rod 10. The second clamping seat 9 is then adjusted by sliding the guide tube 11 and guide rod 10 until it is on the same vertical plane as the first clamping seat 8, allowing for structural adjustment. After the section is positioned, the rotating toothed plate 12 drives the internal threaded sleeve 5 and the upper mounting seat 2 to reset, causing the second clamping seat 9 to close with the first clamping seat 8. Under the sliding structure of the guide tube 11 and the guide rod 10, it adaptively adjusts, causing the first clamping seat 8 and the second clamping seat 9 to fit perfectly together and fix the pipe. Then, the rotating adjusting bolt 13 drives the internal threaded sleeve block 14 and the toothed plate 12 to descend vertically, causing the toothed plate 12 to engage with the toothed blocks 16 on the top of the two sets of guide tubes 11 inside the upper mounting seat 2, so that the toothed blocks 16 and the toothed plate 12 are engaged and fixed, thereby limiting the assembly position of the second clamping seat 9 and the first clamping seat 8, preventing the fixed pipe from shifting or shaking, and improving the stability of the pipe installation and fixing.
